Jofi Joseph: Obama White House Aide Fired for Secret Twitter Account

Jofi Joseph, the White House official who was fired last week for running a secret Twitter account that criticized his bosses' policies, apologized Tuesday night for the insults and for spilling internal information on the Obama administration.

Joseph, 40, who worked as a director in the non-proliferation section of the National Security Council, reportedly operated a Twitter account under the handle @natsecwonk that tormented politicians and White House staffers for two years. Bashing everyone from former Secretary of State Hillary Clinton to top NSC official Ben Rhodes, the comments eventually led to a months-long probe that ended with Joseph's termination last week, The Daily Beast reported.

"It has been a privilege to serve in this Administration and I deeply regret violating the trust and confidence placed in me," Joseph told Politico in an emailed statement. "What started out as an intended parody account of DC culture developed over time into a series of inappropriate and mean-spirited comments. I bear complete responsibility for this affair and I sincerely apologize to everyone I insulted."

Joseph worked as an aide to Pennsylvania Democratic Sen. Bob Casey before joining the NSC nuclear non-proliferation team in 2009

Here are some of Joseph's tweets from the @natsecwonk account, which has since been deleted:

"Vitriol against @arifleischer entirely justified. He married a woman a decade younger than him — and she's as ugly as he is! #jackass"

"I'm a fan of Obama, but his continuing reliance and dependence upon a vacuous cipher like Valerie Jarrett concerns me."

"Does anyone really care what @sulliview thinks? The NY Times Public Editor is a joke. Never seen more navel self-gazing in my life."

"'Has sh—y staff.' #ObamaInThreeWords."

"Was Huma Abedin wearing beer goggles the night she met Anthony Wiener? Almost as bad a pairing as Samantha Powers and Cass Sunstein"

"Interesting factoid: Both Tom Donilon and Tony Blinken once worked for Biden. Both of their wives work for the VP today. #incestuous."

"Look, [Republican Rep. Darrell] Issa is an ass, but he's on to something here with the @HillaryClinton whitewash of accountability for Benghazi."

"Loved, LOVED the @NYTimesDowd column eviscerating the Clintons today. @ChelseaClinton seems to be assuming all of her parents' vices."

Joseph is also suspected of running a second anonymous Twitter account, @dchobbyist, which published "racier tweets about sexual encounters, escort services — and the inner workings of the State Department," according to Politico.

It has not been confirmed whether Joseph was responsible for that second account, as he did not respond to requests for comment.
